ORE-CONCENTRATOR.

Specification of Letters Patent.

Patented Aug. 4, 198. i

Application led. February 19, 1906. Serial No. 301,728.

' T o all whom it may concern:

- of Fort Wayne, in the county of Allen and State of Indiana, have invented cert-ain new and useful Improvements in Ore-Concentrators, of which the following is a specification.

This invention relates to improvements in ore-concentrators, and the object thereof is to effect the removal of mineral from the concentrating table as rapidly as the same becomes clean, and this is done by providin local washing surfaces adjacent the minera discharge side of the table, and suitably supplying the sarnewith dressing water; and', also b v the particular form -`cf. the concen-` trating table.

My object is accomplished\-.by the construction illustrated in the accompanying drawing, in which:

Figure 1 is a plan view of my in ention, a

ortion of the drossinfr water supply pipe being shown cut away; iig. 2 is a detail View showing an elevation of one of the adjust-xp able sup orting struts for the table; F i Sis an end e evation of Fig. 1; Fig. 4 is a etail in perspective showin the lower portion of the concentrating ta le, and particularly showing the arrangement of riflles; Fig. 5 is a detail lan view showing part of 'the mineral disc iargc side of the table, and approximately showing the course of ore matter where dressing water is applied; F ig. 6 is a detail view showing a central cross-section through a portion of the concentrating table; Fig. is a sectional view of the table in a vertical plane adjacent to and parallel with the breast-board, showingr the relative heights of the rillles.

Similar numerals of reference indicate coi*- responding parts throughout the several views, and referring now to the same: 1 is a concentrating table of rhomboidal form and suitably supported u on swinging struts 2, 3, 4, and 5 respective y. The struts 4 and 5 are made wide at the base to revent the table from moving longitudinal y, and the struts 2 and 4 are made vertically adjustable by means of screw-threaded Shanks 6 so that the table 'may be adjusted to have proper incline towardthe mineral discharge side 7 thereof. The struts2 and 3 are sup orted at their lower ends respectively upon locks 8 which are .contained in corresponding cyl'- inders 9, and said blocks are adapted to'be adjusted vertically by means of correspondin'nr wedges 10 which extend through said cy inders. These wedges are connected together by a rod 11, and arc adapted to be moved in unity b means of the lever 12 which is connecter with one of the wedges by tde rod 13. lVhen the struts 2 and 3 are thus moved verticallv the table will thereby be adjusted accordingly with more or less longitudinal decline. A breast-board 14 extenils along the 'lower side of the table, and

a head-board 15 is similarly arranged across the upper end of the table. The table has a covering 16 of suitable material, such as llnoleum, upon which are arranged luunerous riifles 17 and 18. The ritfles 17 extend' from the breast 14 across the table to the mineral discharge edge 7 thereof, and the rifes 18 intervene between the riflles 17 and extend from the breast, parallel with the former-riflies, and terminate upon the surface of the table a suitable distance from the mineral discharge edge 7 thereof.. All of said Thus it will appear that is provided between-the ends of the short i rifiies 18 and the mineral discharge edge of the table.

A feed box 23 is secured to the head board 15, and overhangs the u per end of the table. The feed box is provided with openings 24 in its bottom, and vertically dishosed ribs 25 are secured to the inner side of the feed box at points intervening between the openings 24 and serve to 'prevent pulp from banking toward the out-er end of the feed box. A feed pipe 26, for dressing water, is suitover the minera discharge ortion of the table. tions 2S located respectively-so that dressin water from the feed oipe will be discharged upon the local was ing surfaces approxi-K '95 ably supported u )on standards 27 and ranges This feed pipe has suitable perforamately at points indicated by the dotted ciracting against one side of the driving head 31,

. A l I and the buffer acting against theV opposite side thereof so that a differential reciprocatvinto the feed box, from whence it ing' motion will be imparted to the table. The driving mechanism is so-located in relation to the table that the motidn of the latter will be transverse, or directly'in line with the length ofthe riiiles.

laterally, and isi-adjusted to ran e upon an incline from the breast toward t e mineral discharge edge, and upon a decline from the head board toward the lower, or tailings discharge, end thereof. Ore pulp is then fed asses through the openings 24 onto the suriace of the table. Because of the longitudinal decline of the table, the pui will move-towerd the lower end thereof and) ferential motion and at-eml incline ci the table', together with the Iii-Ties, the mineral portion of the pulp Willbe directed from .beneath the pulp out upon the local Washing surfaces 19 where it is subjected to treatment by dressing veter. The entenditr riiies- 17 conserve the minernl upon the acont local washing surfaces end urther'serve to direct the minersl to the edge 7 f the table irom whence it is discherged into the concentrates' launder. B' this/arrangement the partially concentrate mineral is treated locelly in masses to the action oidressing water, in

'contra-distinction to the common practice of 'applying dressing Water to the partially concentreted miners, in general. Q

A feature or this invention 1s that the table is'so shaped, proportioned, and arranged that the-dengue moves. lengthwise over the table andlbecornes discharged irom its lowerend,

and the minerslis conveyed to.' and di`s-- charged from the upper side di the table, 'and 1t should he pertieulecly noted that the nuneral dischnrge side of length es compared Y t 1 1 1 l' with the `tciimge olscnnigs end thereof. Flins the'gsngue 1s nis-de to revel the full length of the teble while tne inmoral moves the breedth of the table, which errengement iacilitatessettlenient oi velues contained in 'the pulp and the iinsl treatment bx dressing water.

I have found that by placingr a high rifiie 36st theloiver end of the table, and occasional high riles v37 among the other riii'les upon the table, the iionv of pulp along thebreastside oi the table Wfil be retarded somewhat, and the ore-matter will. thereby become suspended in the bodies of Water occasioned by the high rifiies, and thishas, the ef-` feet of facilitating settlement of mineral con tained therein.

All of the high fifties taper from vtheir inner ends at the breast to their outer ends', and are successively of vincreased height from the surface ci the table, the'highest riiile 3 of y In the operation of this invention .the table' 1s set 1n. repid differential oscillating motion .because of the difi table is proportion-`- if Y which is located ai the low or discharge eno. Ythereof. #All Y the riflies, 17 and 18, other',- than' the former. high riiiies taper from their. inner ends at the breast\to their outer ends l and are successively ofless height toward the low'end of the table. That is, the taper of the rilles decreases successively towardthe low end of the table, so that all of the latter riiles will have en equal projection 'fror'nthe I surface of the table approximatelyalong the" line Z-Z. This arrangement of ritiies has the eifect of relieving the overlying ore-mat# ter so that itwvill move toward theflo'we'st corner oi the table (indici` ed at hV-and awa from the Washing surfaces 19; w e the'hig ritiles maintain bodies of water which flood;

the low sind thereby prevent the latter from-causing eddies. l

\-. In Fig. :s shown e transverse central sec-'A tion through the in inernl' discharge side of4 the table. :in view the table is shown -to have 'en inc-line o slightly less degree 'fromthe point Y to .thedncherge edge 7. as co`m-` pared with the incline from 'the breast to the point Y. The noint Y .is lc Ledbetfrreenthe. outer ends of tne short Q18 (indicated at X) and the discharge edge 7.. Y, The dcre'ase in the incline ci tno titille is coincident With the local washing surfaces sind is made to facilitate the discharge of mineral.

Having described' my: invention, what I 'claim as new end desire to secure by Letters Patent is: A h
